Type 26 frigates: new info and some thoughts


My earlier post on the reported troubles with firming up costs for the Type 26 and with getting to contract award have been generating a healthy discussion in the comments section, and that is great. Someone has been reading in my post a sort of hostility from me against the Type 26. I deny this very firmly. My point is another: for what we know about the ship requirements (settled in May 2012 and stable since then) and MOD-endorsed design (which has been frozen in its main lines for quite a long while, now), there is nothing excessively revolutionary that should make this platform unaffordable, considering how much equipment will be carried over from the Type 23 frigates.
It is not my invention, but a fact, that the Royal Navy has deliberately shaped Type 26 as a program which builds on earlier, incremental improvements adopted on the Type 23s and then moved across, without seeking innovation at all costs. A rough figure has been suggested, putting Type 26 in the field of "80% old, and 20% new".
This does not mean that Type 26 won't deliver a step change in capability from the current Type 23s, but rather that it will deliver so using already existing technology, and indeed re-using a fair amount of equipment.
The savings obtained by re-using equipment and by sticking with proven technology and systems are to be employed, in the idea behind the programme, to ensure a decent number of hulls get built, and to ensure that those hulls come with some new and exciting capability thanks to their large size, large aviation spaces and vast "flexible" mission space and, importantly, a large vertical launch silo that will open up routes the Type 23 has simply never been able to pursue.
I very much like the general idea, and my only wish is to see it working as intended.

I'm writing this new article because i've come across some excellent material that provides some great details about the Type 26 design that has been finalized and is being costed ahead of the Main Gate. The document is a letter, dating October 2014, from the Secretary of State for defence to the house of common's defence committee. The SoF replies to a series of direct questions, and provides some excellent information.

First of all, the Flexible Mission Bay. There is no indication of its size and shape, but the SoF finally provides a confirmation that the helicopter hangar is directly connected to the Mission Bay, with a passage large enough to enable the transfer of manned and unmanned aircraft from hangar to mission bay.
Hangar size unsurprisingy at least matches that of the Type 45: the destroyer is slightly larger in beam, but the hangar is not full-width, as it has the RHIB bays on both sides. On Type 26, there are no boat bays, although it is likely that the helicopter bay will be flanked by logistic and aviation stores spaces and by the delivery end of the new mechanized Air Weapons Handling System, designed by Babcock, which is to store, retrieve and deliver the weapons for the embarked helicopter to the Weapons Preparation Area.
Apparently, the AWHS will also handle the Stingray torpedoes for the ship's launch tubes (if they will be fitted, see further down in the article).
The hangar thus can be assumed to match the Type 45's one and it might actually be larger: the SoF says it "comfortably" fits one Merlin or 2 Wildcat. Using the Mission Bay space, more aviation resources could be carried: UAVs, both fixed and rotary wing, but also additional manned helicopters. It would be possible, albeit with limitations, to embark a second Merlin in the Mission Bay, the SoF specifies.
The ability of the mission bay to communicate directly with the hangar (and thus with the flight deck) is an eminently sensible feature to have, and it is good to have the confirmation that it will be there, and with ample chances of exploiting it over the long life of the ships (at least 25 years of design life).

It is also confirmed that the Flight Deck is being sized to allow a Chinook to land and deploy the ramp to enable comfortable embarkation and disembarkation. The compatibility with Chinook, while not strictly necessary, is useful as the heavy transport helicopter could make good use of the ample Embarked Military Force contingent that can sail into a Type 26, and it could also be used to bring aboard capability modules and stores.
Moreover, the Chinook-sized deck should also, and probably mainly, be seen as a way to ensure that simultaneous UAV and manned helicopter operations can happen with suitable space available for necessary deconfliction.
These features add a huge amount of flexibility to the design.


The mission bay itself is a large open space stretching from side to side, with large doors on both sides for deploying boats, unmanned surface and subsurface vehicles, as well as to embark mission modules which can come in containers as big as 20 feet standard TEU.
The mission bay can hold up to four 12 meters boats (and probably a few containers of additional equipment in the middle of the bay, judging from images seen this far) or up to 10 modules / 20 foot containers.
This flexibility will be invaluable in adapting to future missions and in enabling the adoption of future unmanned vehicles which are almost certain to become not just the main MCM system, but also more important in ASW. Having space and infrastructure is, consequently, very desirable for warships which have to last long into the future.
The UK is actively collaborating with France to develop modular payloads for MCM operations, and such developments are happening in other nations across NATO: the UK has taken the lead, according to the letter, for a project that aims to set international standards for the module interfaces, so that foreign systems in future can be embarked and operated where necessary.
One thing which isn't yet detailed is what kind of equipment the ship will have for embarking and disembarking containers and modules: will she depend on external infrastructure, or will the slide-out gantry crane be able to lift not only boats, but also the containers? It will be interesting to see which solutions are adopted. The mission bay will require a strong deck, as reinforced as the flight deck itself. A fully loaded TEU can weight some 24 tons, so a useful payload margin of at least 240 tons is apparently requested. The mission bay estimated size, considering what it can fit, is probably not inferior to a 15 meters long, 20 wide space.


The Type 26 will have a crew of 118, and room for 72 other personnel for the aviation element, for boarding teams, pre-landing forces of the Royal Marines, or for specialists coming to operate the modular mission systems. From the SoF letter, it becomes clear that some real attention has been paid into giving the frigate excellent capability to host the Royal Marines pre-landing party.
In recent times, HMS Montrose, a Type 23 frigate, experimented with a sizeable pre-landing force of over 70 Marines in 2012: must have been a real tight fit on a Type 23, but on the Type 26 there will be space and infrastructure to do much better.

In terms of weapons fit, the letter specifies that the vessels will be fitted at build with a sizeable Flexible Strike Silo numbering 24 cells, for anti-ship, land attack and anti-submarine weapons. The letter specifies that the cells will be american MK41. This is a surprise, since earlier info suggested that since MK41 is somewhat larger than Sylver modules, only two launchers (for 16 cells in total) could be fitted: it appears it is not so, and the higher number of cells has been confirmed in the finalised design.

Confirmed are the 48 Sea Ceptor canisters as well, almost certainly in the two silos configuration seen in CGIs and models so far, so with 24 cells on the bow, ahead of the strike cells, and 24 aft of the funnel mast, amidship.
The Type 26 will have a 127mm gun, too, replacing the old MK8. I'm told that, although it has not yet been officially announced, only the MK45 Mod 4 remains in the frame, with the Oto Melara 127/64 out of the race. Jane's had reported a while ago that the MK45 had been given preferred bidder status, so it seems things are moving in that direction. The new gun will "allow" the Navy to buy into the new long-range guided ammunition being developed for the calibre, which is a NATO standard, unlike the 114 mm of the MK8.
There will also be two 30mm light guns, as expected, and the possibility to fit two Phalanx CIWS.

The list shown in the letter comes without one notable piece, however: it makes no mention of Stingray torpedo tubes, which is very surprising considering that the Type 26 is an ASW platform, and that the launcher systems could reasonably be transferred from the Type 23s.
It is an omission that causes questions to arise: it seems unlikely that there would not be such a fit on this kind of vessel, especially since vertical launch anti-submarine rockets, which are mentioned in the letter, are not in british service, and would have to be somehow procured (read: financed, as that is the issue). It is not a product line where there is much choice: the americans have the ASROC, the italians have the MILAS (which is not vertically lauched, however) and the South Koreans are producing a system of their own. Japan also has its own anti-submarine missile system. None of these is fitted with a british Stingray torpedo, obviously, although this could probably be fixed quite easily.
Not fitting the torpedo tubes would be a puzzling decision, if confirmed. The ship's tubes are admittedly more of a snap self-defence fit than anything else, considering the limited range of the lightweight torpedo fired from them means that the frigate launching them would probably already be under attack by the enemy submarine; but doing away with them entirely, besides while not having a clear path to a vertical launch solution, is questionable.
Might it be just a case of them having been "forgotten" in the letter? Can't be excluded.

The letter also has another nice little bit of a news in itself: the FASGW(L) missile, the Thales Light Multi-mission Missile, has been given the name MARTLET in british service. This hadn't been disclosed to the public before, as far as i'm aware, unlike Sea Venom which was named earlier this year.

(Secretary of State for Defence - Type 26 letter to the defence committee)




A displacement of 8000 tons? 

Type 26 is going to be a large and "dense" warship. The 6000 tons displacement quoted by BAE is pretty much certainly not the weight of a fully loaded Type 26, and indeed some recent news reports have suggested that the ship might now be an "8000 tons full load displacement vessel". I'm however not sure i can believe the 8000 tons value at this point, because it sounds excessive in relation to the specifications and the size of the vessel, but it will be an heavy ship, that's for sure. The SoF letter does not provide any helpful indication about this subject.

Type 26 is 148,5 meters long and around 20 meters in beam. Not too far from the 144,6 and 19,7 meters of the italian variant of the FREMM frigates (the french ones are slightly shorter, as the italian ships are being lenghtened post-build by some 3,5 meters adding an additional section in the stern) which have a declared displacement of 6700 tons, sometimes indicated in more than 7000. The italian navy has released some different, contradictory figures for the displacement, which consequently isn't identifiable with certainty. Even the reason for the lenghtening isn't yet fully clear: officially, the expansion was mainly due to the need to improve all-weather operations with the AW-101 Merlin helicopter and was exploited to provide additional accommodation space, 100 tons of additional fuel (bringing endurance to 6700 nautical miles against 6000 earlier) and a second RAS station. The weight increase coming from the lengtening was indicated in 250 tons.
Unofficially, there have been strong suggestions that the lenghtening has been inspired by the wish to correct weight distribution, as the italian FREMM have been given the same huge main mast of an Horizon destroyer, carrying the heavy, powerful EMPAR radar system, and this has, again reportedly, made the ship remarkably bow-heavy, with consequences on handling, particularly in rough seas.

In many ways, the italian FREMM is a good comparison to Type 26: the italian navy is taking delivery of two variants, the General Purpose and ASW. The first replaces the towed sonar of the second with a stern ramp for the deployment of a 11-meters RHIB. The other main differences are that the GP is armed with a 127 mm gun and a 76 mm gun-CIWS, while the ASW has two 76 mm guns. The GP is, for now at least, not fitted with the SLAT anti-torpedo decoy system, which is instead standard on the ASW.
Both ships carry two helicopters in two hangars: one, slightly larger than the other, can house an AW-101 Merlin, while the other is sized for the NH-90 helicopter. The frigates can employ one AW-101 and one NH-90, or two NH-90.
In fairness, i've heard comments suggesting that the AW-101 hangar is quite tight, and considered more adequate to carry a NH-90 and offer spaces for its maintenance rather than allow the actual enduring embarkation of an AW-101 Flight. The smaller hangar bay has been described as just large enough to house the NH-90, without work spaces, so it does seem more practicable to go with two NH-90s, which is by the way more likely as Italy is procuring 40 to 46 NH-90 NFH, while the AW-101s are much fewer (10 ASW, 8 amphibious assault / transport and 4 AEW) and generally meant for use on the Cavour aircraft carrier.  
Both ships employ one 11-meters RHIB and one 7-meters one, with the GP adding a second 11-meters in the stern, as already said.

It would be interesting to have an accurate displacement value, as it could provide a useful ballpark idea for what the Type 26's own displacement might be.

The italian FREMM has accommodation for at least 200 following the modifications (180 on the french FREMM), but also has a core crew considerably larger than the french variant (108 including 14 men of the helicopter flight): the GP was meant to have a crew of 131, and the ASW of 133. Use of the platform at sea has since inspired an expansion of 34 men, as well as some 23 for the aviation department.
The increase in crew size has had some impact on the vessel: currently, the space originally preserved to fit two 8-cell Sylver A70 launcher modules for strike missiles has been sacrificed to provide additional accommodation spaces.
The standard of accommodation, especially in the original rooms, is very high. The room with more bunks has only 4 beds. That's a lot of volume used in what does not appear to be a very efficient way.  

The Type 26 is aiming for a core crew of 118, with accommodation for another 72 personnel. On the Type 45, junior rates sleep 6 per room. On the Queen Elizabeth class, the 6 bunks rooms are larger, but come with two folding beds which can be used to embark 2 more personnel.
On the Type 26, which will need some pretty well optimised use of space for fitting accommodation for 190 plus a large flexible mission bay and a substantial number of VLS, the arrangement of bunks has not yet been detailed. However, back at Euronaval 2012 some reporters talked about 9-bed rooms, a bit of a sacrifice in terms of crew spaces to make everything fit.

Sensor-wise, the italian FREMM is fitted with the EMPAR, as said earlier, a system considerably larger than ARTISAN 3D: the antennas of the two systems weight 2,45 tons against 0,7 tons.

In armaments, the italian FREMM carriers two 8-cell Sylver A50 modules, with the SAAM - Extended Self Defense control system, which enables limited area defence employing not just Aster 15 but Aster 30 as wll. The limitation in area defence performance comes, effectively, from the fact that the FREMM does not support the EMPAR with a long-range radar as happens instead on the Horizon destroyers.  
Type 26 will be able to employ up to 48 CAMM / Sea Ceptor missiles, distributed in two silos. Weight-wise, despite the big difference in numbers, it is the SAAM-ESD that weights the most, since each Aster 15 in its canister weights a full 550 kg, with Aster 30 reaching the 700 kg, while each CAMM canister is in the region of the 100 kg, and being a cold-launch weapon it does not need a VLS as bulky and complex as Sylver (over 8 tons per module, but exact weight not available).
The FREMM armament is completed, in the GP case, by a 127/64 gun (34 tons with turret ammunition drums filled with 56 shells) plus 305 shells in an automated handling two-storey ammunition depot; two 25 mm guns, two triple MU-90 torpedo tubes, eight TESEO anti-ship missiles (770 kg each in their canister) and a 76mm gun on top of the hangar, weighting 7,9 tons without ammunition.

The Type 26 however will have, as of October 2014 information, 24 MK41 strike lenght cells available in addition to Sea Ceptor. Each module, bare of weapons, weights some 14,5 tons. If each cell was filled with a MK14 Mod 2 canister containing a Tomahawk missile (the heaviest, at 2,777 kg each), the weight would rise rapidly! The maximum weight of the Flexible Strike Silo, launchers plus Tomahawk canisters, could be in the region of an impressive 110,15 tons.
However, to this day there is no real indication yet of what the Royal Navy wants to fit. Tomahawk appears to be likely, but the Royal Navy also needs to replace Harpoon, and the only MK41 candidate which could be readily available by then would be the american LRASM solution. The anti-submarine "rocket", if it will be actually pursued at some point, would be another novelty.

The italian FREMM carries enough fuel for 6700 nautical miles, and enough stores for 45 days, officially. The Type 26 reportedly aims for no less than 7000 nautical miles and 60 days, so there might easily be dozens of tons of difference in the amount of fuel carried, and a significant difference in the volume and weight of stores, as well, but providing exact figures is not possible at this point.
The propulsion systems have in common the presence of a gas turbine and four diesels, but that's about it. The italian FREMM uses a 32 MW LM2500+ G4 gas turbine and 4 Isotta Fraschini VL1716 diesels and 2 Jeumont Electric motors, while the Type 26 will have a 36 MW Rolls Royce MT30 and 4 MTU V20 diesels generating 12 MW. However, the FREMM is a CODELAG ship which can run the gas turbine and the diesels at once to sustain high speed in rough sea or obtain greater max speed, thanks to a RENK 170-175 gearbox set weighting some 120 tons; while the Type 26 will be CODELOG, which means the diesels will be used to generate electric power for silent cruise speed, but will be detached when max speed is requested, leaving the sole MT30 to directly drive the two shafts.
The electric motors of the Type 26 are to be supplied by General Electric, and the gearbox by David Brown.

Overall, it is quite natural to expected a loaded Type 26 to exceed 7000 tons and the weight of the slightly smaller and less armed FREMM, but 8000 tons would seem to be an exaggeration.



Costs  

It is a good thing that the Type 26 does seek to reuse much of the expensive equipment fit (main radar, Future Local Area Air Defence System / Sea Ceptor, light guns, navigation radars and other equipment) and build on existing technology (including the shared infrastructure common combat system, which is being rolled out across the Royal Navy's surface fleet in the coming years, having already been installed on HMS Ocean, ordered for the Type 23s and mandated for the new build OPVs), because otherwise there would be no chance to meet the ambitious cost targets set for the programme.
The hull is going to be big and capable, and very dense, with such big spaces being requested for the Strike VLS, mission bay, fuel and stores. The Strike VLS fit is not new (it builds on something that is operational on hundreds of ships around the globe) in general terms but is a new entry in the Royal Navy, so will need to be acquired anew.

Ultimately, we do not know which is the current target pricetag for the Type 26. The newspapers have recently made headlines about Type 26 being a 4 billion project, but this isn't too helpful because government has notoriously indicated that there is likely to be a first contract for 8 ships, to be followed (hopefully) by 5 more later. If 4 billion applied to the first 8 hulls only, the cost per ship would 500 million pounds, rather non ambitious at all. On the other hand, 4 billion for 13 ships would likely be too little, at little more than 307 million per hull. Result maybe not beyond the realm of the possible in general terms, but looking too ambitious for british shipbuilding, which isn't really famous for being cheap.

Maybe the danes could get it done: they have very successfully built the IVER HUITFELDT class frigates, three capable air area defence warships which have cost an amazingly low 313 million USD each.
These impressive vessels, however, build their hulls on the experience of the commercial operator Maersk, a factor not to be underestimated. The design has also benefitted from previous work done to design the Absalom class, another success story.

The IVER class use a fully-diesel propulsion with 4 large MTU sets which can push the ship for 9300 nautical miles at 18 knots, but that can also thrust her to over 29 knots speed with a 120 seconds acceleration time. The base crew of 116 isn't too far from Type 26's target, nor is total accommodation available, set at 165+ men.
The IVER is a 6649 tons displacement vessel, about as large in beam as Type 26, but around 10 meters shorter.
The ships are fitted with an advanced combat system and with the excellent APAR multi-function radar used also on the german SACHSEN ships, supported by the SMART L, the long range radar which equips the Horizon and Type 45 destroyers (in the S-1850M variant). They have a 32-cells MK41 Strike Lenght silo amidship, supplemented by 24 additional cells for ESSM missiles and by space for more ESSM or for up to 16 Harpoon. They are fitted with two 76 mm guns, and a Millenium CIWS, but could soon enough swap one 76 for a MK45 MOD 4 gun. The other 76 could stay or be replaced by another Millenium.



Amazingly cheap, these ships deliver formidable value for money. The budget for all three was 940 million USD, supplemented by 209 million in re-used equipment (ESSM cell modules, Harpoon and 76 mm guns, mainly). The budget did not include the purchase of the SM-2 missiles for air area defence, so for now the MK41 is empty and only ESSM is available, and the 127 mm gun is planned but not yet purchased.
Deep in the hull, they have space reserved for a towed sonar, and further space for other equipment with a footprint equivalent to four 20 feet containers. 







It will be a big challenge for the british shipbuilding industry to keep Type 26 costs down. There is no revolutionary system being requested, but on the other hand there is admittedly quite a lot of capability being designed into a dense hull.
The amount of re-use of existing equipment migrating from the Type 23 could be a real lifesaver for the programme: the abundant carry over should represent a big "saving" of sort (money will have of course have been spent for all items, but early and separately), especially since it covers most of the big-money items of the combat equipment.

Saying how much it will cost to fit the new MK45 main gun and the MK41 silo is not easy, but thanks to an immensely useful USN document detailing the cost of new build DDG-51 destroyers by major subsystems, i've put together a ballpark estimate. Take it with prudence and salt, of course: this is a very rough method for estimating costs, but i think it is interesting enough to be included as a basis for discussion and reflection.



To provide a rough cost indication, i've scouted US Navy documents which helpfully provide a major breakdown of the cost of a DDG-51 by major subsystems and related components and activities, looking at the years 2013, 2014 and 2015. There are, as always happens in these things, some pretty large variations in price from a year to the next, but it is at least possible to get an idea. The yearly data suggests that ordering many in the same years significantly lowers the costs with economies of scale. (USN document)




The MK41 fit on a DDG-51 is a 12 launch modules affair, with a cost in the region of the 48 million dollars. 12 modules, however, are the fit of 4 Type 26s, according to the info we now have. So it might take around around 160 million USD to put 24 MK41 cells on all Type 26s. Rough estimate, of course, i want to say that again. The number of modules is lower per hull, but there are more ship sets. However, there should not be a big difference per se in terms of ship sets installation. Dropping 36 modules in three hulls or 39 in 13 hulls shouldn't be excessively different, but for the fact that they would be separate operations happening on different years. This might raise the cost, but overall i would like to think that things would even out in a reasonable way.

If it is decided that the Type 26s have to be able to successfully employ Tomahawk, they need the Tactical Tomahawk Weapon Control System fit too, and that could require up to some 16 million USD per ship (cost for a single ship set in 2014, the unitary cost drops as low as 11 million with 3 sets in 2013 and 13 million with 2 sets in 2015). 16 million for all 13 ships would add up to 208 million for the class. Again, rough estimate. All costs inclusive of technical support, engineering, initial spares etcetera. I don't know if LRASM has a comparable, separate mission planning system. Probably not, but there would be of course integration costs of its own with it having its own backend in a shape or another.

The rest of course depends on the missile, and how many All Up Rounds are purchased. The last Tomahawk contract, which included 20 submarine torpedo tube TLAM for the UK, was a firm fixed price order for 231 rounds (147 Vertical Launch rounds for US surface warships, 64 encapsuled rounds for US navy submarines with VL cells and 20 torpedo tube launch TLAM rounds for the UK) for 251,13 million dollars.


In theory, and i'll say it again in theory and in rough estimates, 24 MK41 cells + Tomahawk mission system + 231 missiles (using the 231 figure and its cost, even though the torpedo tube missile is more expensive than the VL) = 619.13 million dollars, or around 396 million pounds, at today's rates. And that's with a 231 TLAM order thrown in for good measure, that we all know isn't going to happen. Probably there would be a finite, much smaller number of missile loads purchased, and the deploying ships would stop by the Upper Harbour Ammunitioning Facility prior to deployment to take the rounds on board, since pretty much never are we going to see all 13 vessels on operations at once anyway.

All this, just to have a ballpark idea based on something. Better than speaking purely on wild speculation.
If you follow the link to the US Navy document, you'll see that it quotes Unitary Item Costs which are all much lower than the amounts i used. I did that deliberately, by looking at the total expense per ship related to the various items so to include, albeit of course in a rough way, the spares, engineering and services costs which are very much inevitable. Using the unitary cost alone would not be realistic, as the amounts resulting would be much lower than the real ones. In this other way, the cost figures should be much closer to the truth. 
This is mainly to indicate that it won't be the fitting of MK41 launchers that will break the programme's budget on its own: they fit 32 MK41 cells on the cheapest high end combat ships out there, as we saw.

As for the MK45 Mod 4, it is also of some interest to see its cost is in the region of some 25 million apiece, apparently. Again, the cost for a british purchase might be different, and it is indeed likely to be somewhat higher since for the UK it will be a totally new system, while it is business as usual for the US Navy. 



In this long piece, i've wanted to share the quality info i've found about what the design of Type 26 offers, and i've also tried to explain why i talked the way i did about the reports of cost issues and the delay in clearing Main Gate. The requirements, taken as a whole, are ambitious in several ways, and i won't deny that. But they have maintained steady over time, and they are being mitigated by a responsible approach to the programme. I hope that now the whole package can be made to work, and work well. Because one thing is certain: this programme is of vital importance to both the Navy and the british shipbuilding industry. It is in the interests of both that it goes as planned. 
If it did, it really might be a renaissance for british yards, because this ship, while not revolutionary in its subsystems, is very much (r)evolutionary in terms of what it delivers as a whole. A good product at a reasonable price: what is needed for the Navy to survive, and for export orders to return to british shipyards.

Royal Navy surface fleet: the coming years



In a break from the Army 2020 saga which has for quite some time now been the main focus, i've wanted to work on some interesting new documents i've found, to put some order in the current plans of the Royal Navy surface fleet for the future, starting from the Type 26 design, which is maturing quickly. 



Type 26 frigate

“There will be no more destroyers or frigates. There will be combat ships.”

The quote is from Cmdr. Ken Houlberg, Royal Navy who, until August 2012 , was the Capability Manager for Above Water Surface Combatants at the MOD. As such, he was the man in charge of the ongoing plans to design and build the new Type 26 Global Combat Ship  and, equally important, the developing plans for the Type 23 Capability Sustainment Programme.

We have to keep in mind, after all, that the last Type 23 is only expected to bow out of service in 2036: for many more years, the 23s will continue to be a fundamental part of the fleet, and for well over a decade they’ll serve alongside their successors. 

Another point he made is also absolutely worth highlighting: “These ships will be the spine of the Royal Navy. But they will be expendable. The day we make our escorts so expensive that they become strategic assets is the day I suggest we got it wrong.”

The Royal Navy is fully aware that the costs of the Type 26 frigate program must be kept on a tight leash: there must be no escalation. Either they are affordable, or the fleet will be in deep trouble.

The Royal Navy is trying to be considerably careful about what it asks for. It has been very openly admitted that, if 80% of the Type 45 destroyer was about innovation and revolution for the fleet, the Type 26 will be 80% about careful evolution of capabilities already available. The expectation is that several important elements of the ship’s equipment will cross-deck from Type 23 frigates decommissioning, in fact.

There have been doubts and disappointments voiced over this approach, and the validity of the whole Type 26 has been contested by some commentators, but personally I believe this is actually a completely valid approach. Besides, the emerging Type 26 frigate promises to deliver major improvements and great capability despite the relative “conservative” design philosophy.

Commander Houlberg, speaking in October 2012, shared some details on the MOD-endorsed Type 26 design: no shocking revelation, but several welcome confirmations of data you’ve already had the chance to read on this blog.

First of all, the Mission Deck, which originally was to be located in the stern but actually moved upwards, to Deck 1, adjacent to the helicopter hangar. Despite the move, Houlberg confirms that it remains a large reconfigurable space, with an available volume for 11.5 TEU containers and/or boats (up to four 11.5 meter boats) and unmanned surface and sub-surface vehicles. This confirms data which is also reported on the BAE Global Combat Ship website, but which appeared doubtful and possibly outdated. Now we know that it is not the case: the Mission Bay remains as part of the design, and continues to offer considerable amounts of useful space for the embarkation of mission modules of all kinds, such as a containerized field hospital or accommodation modules for an additional 84 troops, or command and control facilities. Crucially, this space will be available to carry air, surface and underwater unmanned vehicles which, in a future not too far, could be an absolutely crucial component of the ship’s combat system. 



The above image, courtesy of http://navy-matters.beedall.com/, shows a now old Thales concept of reconfigurable hangar and Mission Space, which was proposed for the Future Surface Combatant, now Type 26 Global Combat Ship. The image is still relevant, as it helps giving an idea of what the current hangar + mission bay arrangement could be like. 
 

We do not yet have a map or graphic representation of the current Mission Bay layout. I’ve made a guess already some time ago, but I hope we will be given some official indication in the future.

The move from stern to Deck 1 is reportedly due to several factors: the need for a wide, spacious mission bay conflicted with other requirements that the Royal Navy prioritized. Above all, acoustic quietness of the hull design, which has been the most pressing requirement all along. In addition, the free head available in the stern area was going to be very limited, and the low freeboard needed for boat operations via stern ramp was in conflict with stringent damage control requirements.

Last, but not least, the stern boat ramp and mission space conflicted with the installation of the towed torpedo decoy and of the 2087 towed sonar, introducing some serious challenges.

The move to Deck 1, on the other hand, implies boat operations will be more complex than they would have been with a ramp available in the stern. The decision was nonetheless made to go ahead with the move, meeting the challenges of boat launch and recovery with two motion-stabilized davits, port and starboard.

Houlberg is confident that the Type 26, also thanks to such free, mission-reconfigurable space, will be future-proof, and able to eventual employ railguns and direct energy weapons such as lasers. In the shorter term, the ships are expected to have 48 CAMM missiles in bespoke vertical launch cells, plus up to 24 large missiles including potentially a mix of anti-submarine, anti-ship and land attack weapons. These will be carried in 24 “Strike Length” cells, readily available for use with the Tomahawk and with a future Harpoon replacement. There will be two Magazine Torpedo Launcher Systems, as on the Type 23s, and the ship is planned to do away with the MK8 Mod 1 medium gun, to take aboard a modern, powerful 127 mm gun instead, which will also have the advantage of commonality with most allied navies, from US to Italy. The ship will have the capacity to embark a couple of CIWS systems for self defence, and it will also carry a couple of light guns for surface defence, plus a couple of miniguns and four GPMGs. 


This NavyRecognition photo shows the BAE Systems Type 26 model as showcased at Euronaval last year. I've evidenced the main features of the weapon system.
 



The type of VLS system is not yet decided, by BAE confirmed last January that the Type 26 is designed to be fitted with either the MK41 Strike Length or with the equivalent Sylver A70 cells.

The “RN Type 26 design” exploits the Cold Launch feature of the CAMM missile to locate 24 missile cells in the funnel mast, but this arrangement is not available for use with conventional, Hot Launch missiles due to risks and problems connected to heat and exhausts. Customers, however, which were to buy the Type 26 but require a different air defence weapon, could be given other options, such as different, large array of cells on the bow, or perhaps even a second missile silo in the space that the british variant uses for the Mission Bay.

BAE Systems is offering potential customers a variety of solutions, including a different, integrated mast with AEGIS-type radar aerials. Discussions on Type 26 collaboration have been started with a variety of possible customers including Canada and Turkey, but the most interested are Brazil and Australia. BAE has recently confirmed that a number of Brazilian engineers are involved in the over 300-strong team working on refining and finalizing the Type 26 design, while the UK and Australia have signed defence collaboration deals which include quite a focus on the possibility of walking together down the Global Combat Ship route.

The main gun is set to be either the BAE/United Defense 127/62 MK45 Mod 4 or the Oto Melara 127/64 Lightweight. The first gun has the backing of BAE Systems and is the latest variant of the standard US Navy gun, while the second is possibly the most advanced medium gun in the world and is in use or has been selected for future use by Italy, Germany and others. France is also interested in eventually acquiring the 127/64 LW for at least some of its FREMM frigates, after the experience in Libya in 2011 suggested that the 76mm gun is not really sufficient for what is going to be the main surface combatant in the future fleet.
Oto Melara is bullish on the possibility of achieving an historic win in the UK with the 127/64, and they have chosen an important british partner to work with: Babcock.

Routinely, the ships will embark either a Merlin or a Wildcat helicopter, plus, it is expected, at least one unmanned aerial vehicle, probably rotary wing. It is quite likely that the hangar, like that of the Type 45, will have actually have room for a couple of Wildcats.

The crew will number just 118, thanks to greater automation, but there will be accommodation for 190, leaving space for 72 more personnel. These will be “Capability Teams” of specialists operating in the most diverse roles: it could include anything from Royal Marines to Helicopter Flights to operators of unmanned vehicles and other capability modules.

The ship in addition will have an unprecedented logistic autonomy of 60 days, giving her roughly twice the endurance of a the Type 23’s.   

The Type 26 for the Royal Navy will be built with a CODLOG propulsion arrangement, expected to combine a single gas turbine and four high speed diesel electric engines connected to two electric motors. Rolls Royce confirms It has been contacted, and will make its bid: it is widely expected that its latest “lightweight” MT30 gas turbine will be selected for the Type 26.

WƤrtsilƤ is the favorite for the contract for the supply of the diesels, but the main factor in the choice is to be, again, the ability to run quietly, as the Type 26 will do its ASW work on diesel propulsion. Converteam is  very likely to provide the electric motors.

The Type 26 aims to have the capability to cruise at up to 18 knots with diesel-electric propulsion, and there is a requirement to sprint to speeds above 28 knots using the gas turbine in direct drive.

It remains intended that 13 Type 26 ships will be built, with 8 configured for ASW missions and 5 as “General Purpose” vessels. The hulls will be the same, but the GP won’t be fitted with the towed sonar 2087 and other expensive ASW kit.

This already happens with the Type 23 fleet, with only 8 ships having been fitted with the advanced 2087 towed sonar.

The first Type 26 should enter service in 2021, and afterwards the building rhythm would be of one ship per year, until all Type 23s are replaced. By the end of this year, the team working on the Type 26 design is expected to grow beyond 400, active in Portsmouth, Filton and Scotstoun.



Surface Fleet programs in the Core Budget

An October 2012 presentation from DE&S contains very important information about the Surface Fleet programs featured in the Core budget. As we know, the document released to Parliament about the 10 Years Equipment Programme was extremely poor of details and basically named no programs other than the big ones already contracted for. Practically nothing was said about the large number of smaller programs that sit both in the Committed and in the Uncommitted Core Budget.

It must be remembered, in fact, that only a part of the Core Budget is already contractually committed. Around one half of the Core Budget is currently “uncommitted”: planned to be used for programs that still haven’t reached the point of contract signature. In the early years, up to 80% of the core budget is already contractually bound, but the balance changes rapidly: by 2015, it is roughly a 50:50 balance between committed and uncommitted, and towards the 2020s the balance is 20:80. This excludes the famous 8 billion “headroom”, planned to be available mostly after 2016/17. 
The 10 year Equipment Budget
 

For the Surface Fleet, the core budget for the next 10 years is as follows: 
 

10 year Core Uncommitted budget for warships
 


KIC stands for Key Industrial Capability. These KIC points are agreed levels of national shipbuilding capability that have to be preserved under the terms of the Terms of Business Agreement (TOBA) signed by the MOD with industry. The contract workings are complex to explain, but there are agreed levels of work that the MOD must ensure for the restructured national shipbuilding industry, otherwise a KIC threshold is broken and the MOD is forced to pay to preserve capability. 

RT997 is the new Type 997 radar, more commonly known as Artisan 3D. It is due to become the new standard 3D radar for the fleet, and it will be present on the Queen Elizabeth-class carriers as well as on Type 23, LPDs, HMS Ocean and Type 26. 

Do not be scared by the absence of CAMM/Sea Ceptor from the list, as its costs are part of another budget voice, the "Complex Weapons" one. 

The list of programs relative to warships includes:


Future Inshore Patrol Capability: this program, which from the graphic seems to benefit from a quite large budget (although exact values aren’t disclosed), is connected to the P2000 patrol boats. It might be a replacement for them, or, perhaps more likely, a program of improvements to their capability.

The fitting of armor, better weapon mounts and other improvements to HMS Tracker and HMS Raider, which have been removed from University taskings and assigned to Force Protection duties might have more than a little something to do with this budget voice. 


HMS Raider and HMS Tracker have been removed from University duties and upgraded to better serve in the Force Protection role.
 



 It is not clear if there is any link between this program and the Royal Marines’s requirement for a new, deployable Force Protection Craft.

Surface Combatant Common Core Combat System (SC4S): a Royal Navy effort to evolve combat systems in service across the fleet to build around a common core. Commonality will drive costs down and simplify adoption of fleet-wide improvements and additional capability modules. HMS Ocean, in her currently ongoing refit, will be the first vessel in the fleet to receive a Shared Computing and Network Infrastructure which will be progressively rolled out on the other vessels as well, with the LPDs to follow, before the escorts.

Naval Mode S Interrogators: continued roll out of the Successor IFF technology, with passage from the MK XII (first rolled out in 2003) to the latest MK XIIA Mode 5.

New Navigation Radar (NASAR: NAvigation and Situational Awareness Radar): this program is about the replacement of the aging Type 1007 navigation radar. A competition for the NASAR requirement was started as far back as 2009, with the aim of putting the new radar in service from 2012. Delays followed, and in a 2011 debate in the House of Commons it was disclosed that the ISD is now indicated in 2016.

NASAR’s objective is to select a Type 1007 replacement to be used across the whole RN and RFA fleets.

The contenders are the Kelvin Hugher SharpEye and the Ultra SCANTER 6000. The SharpEye has been selected for use on the new MARS Fleet Tankers, with each ship set consisting of three such radars. This suggests that the Royal Navy has chosen. Unless they have abandoned the proposition of using a single type of navigation radar for the whole fleet, we should be seeing more orders placed in the coming years, starting with ship sets for the new aircraft carriers.

Future Maritime Radar Electronic Surveillance (FMRES): fleet-wide adoption of the latest fully digital Thales Radar Electronic Support Measures (RESM) already being fitted to the Type 45 destroyers.

There is a series of research and development programs for improved Force Protection of warships against ASW and ASUW threats, from swimmers to fast attack crafts.

Maritime Integrated Defensive Aids Suite (MIDAS): this most interesting, complex programme includes multiple activities and objectives. A variety of new RF and IR decoys is to be developed, and there is also a requirement for protection against laser guided weapons.

The current fixed, six-barrel decoy launchers would also be replaced with a new generation launcher. This specific requirement should be known as DAS-SS. The contenders include the Rheinmetall Multi Ammunition Softkill System (MASS) and the Chemring CENTURION trainable launcher. The CENTURION appears in the slide, but the image does not automatically mean a selection has been made already. For sure, the Royal Navy is genuinely interested, and officers will be present at trials of the system planned for later this year. Chemring also firmly believes that the Royal Navy will eventually buy in: the CENTURION’s website is full of images of Type 45s and RN vessels.

The CENTURION is a stealthy, fully trainable turret launcher with 12 independently aimed launcher tubes capable to fire all existing 130mm decoy rounds, and larger ones as well. It can be loaded with multiple different types of decoy at the same time, and its main advantage is its ability to deliver accurate payload placement to maximise decoy effectiveness, regardless of the ship’s position.

Recently Chemring has signed a deal with Raytheon to work on a weaponized variant of Centurion, which will be able to fire not just decoys, but missiles for the defence of the platform, mainly from Fast Inshore Attack Crafts (FIACs). Missiles proposed include the Javelin, the Griffin and even the TOW. 

Almost certainly part of, or directly related to MIDAS is also the ACCOLADE technology demonstration programme, a joint UK/France effort for the development of a new, active Radar Frequency decoy. The contract dates back to February 2011 and has a value of 14,4 million pounds. Field and sea trials should happen in the coming months, before the demonstration concludes, by May 2014.

Other programs and researches connected to MIDAS aren’t publicized. Some high level research is obviously classified, as the Royal Navy places huge faith and importance in the Soft Kill technology, mindful of the fact that, as of December 2012, from 1967 there have been 241 anti-ship missile attacks in the world. Of these, 128 have been defeated by the ships’ defences, with 127 ASMs tricked by decoys and Soft Kill technology and only one stopped by interception (the Silkworm missile shot down by HMS Gloucester in 1991 during operations in Iraq).

One such research has been revealed recently, unfortunately because the MOD has been unable to continue funding it and has authorized Thales UK to seek new partners willing the fund the next phase among a list of allied countries.

The self-defence system that was to come out of this development program sounds very capable and very promising, but it also sounds like it realistically requires quite a lot of funding to reach maturity and be completed.

The system is described as a meter-high laser turret capable to employ up to four or five lasers in different wavebands. The lasers can be used to dazzle or destroy the electro-optic seeker on incoming anti-ship missiles; engage sensors on the enemy platforms firing the missiles, and even act as a non-lethal defence in asymmetric scenarios, dazzling people with an eye-safe laser.    

The DefenseNews article seem to suggest that MIDAS has been shelved as a whole, but I doubt this is correct. Although new cuts have been announced for the MOD in the budget 2013, they are not expected to bite into the core equipment programme. So, at least for now, it is more likely that MIDAS has entered a new phase (perhaps changing name to another impossible acronym, since the MOD loves doing that) and has selected just a few developments to fund, being unable to ensure money for those at a lower maturity level, such as this laser countermeasure. Hopefully, Thales UK will be able to bring other partners on board, to continue development of this very interesting system, which has, in my opinion, great potential. The MOD would then be able to buy the finished product later on, saving money.

The Automatic Identification System (Warship Automatic Identification System W-AIS) is a situational awareness tool which is being installed on all ships of the Royal Navy. It overlay AIS contact data onto Warship Electronic Chart Display Information System (WECDIS). WEDCIS is introducing advanced digital navigation on Royal Navy vessels, including submarines.

Future Maritime Fires System: this program’s main result is the choice to adopt a new Medium Gun starting with the Type 26 frigate. A 127mm standard NATO gun will replace the MK8 Mod 1.

Other offensive weapon capabilities have been studied and are considered, including “deep” integration of the Fire Shadow loitering ammunition for launch from the Vertical Cells of Type 45 and, in future, of the Type 26. 



Fire Shadow at sea
 


FIAC Target (also FIAC RT, Fast Inshore Attack Craft Realistic Target): purchase of training solutions meant to prepare for defence against swarm attacks carried out by small, fast boats, including suicide crafts. This includes purchase of unmanned target boats.

Type 23 Capability Sustainment Programme: covered further down in this article, it is a program of upgrades meant to keep the Type 23 relevant all the way to exit from active service, in the 2030s.

Maritime Composite Training System: the MCTS is expected to become a more and more important and effective way to train crews on land, using advanced simulations to save money.

GWS60 Harpoon Sustainment Programme: the graphic shows that a lot of money is expected to go into sustaining the Harpoon missile to its OSD. It will be interesting to see what choices are made in this area, and what missile will eventually replace the old Harpoon. The Type 26 is, in fact, expected to employ a Vertical Launch weapon: among candidates that have the RN’s eye there is also the Tomahawk IV “MultiMission Tomahawk MMT”, a US-backed development of the cruise missile to make it capable to engage ships in complex scenarios, including in the littoral.

There is also a joint study with France going on for a future cruise and anti-ship missile, with the MBDA Perseus concept being a first indication of what the general thinking is.

Maritime Engineering Development Programme (MEDP): research and development activities covering all aspects of marine engineering technology, including advancements in All Electric Warship configurations, integrated waste management, upper deck systems, fire-fighting devices, roll stabilization etcetera. 

Minewarfare and Hydrographic Patrol Capability: a bit budget is reserved for activities relating to the development of unmanned vehicles for hydrographic and MCM tasks, which will initially be employed on current minesweepers and survey vessels.

Eventually, the MHPC will also deliver a new, multi-purpose ship design to replace the minesweepers and, in time, survey ships Echo and Enterprise. Current indications are for a 2-3000 tons patrol vessel with global range, light armament and the capability to carry the unmanned vehicles needed for stand-off mine clearance and hydrographic survey.

UK Cooperative Engagement Capability (UKCEC): in early 2012 the Royal Navy had hoped to get the go ahead to fit CEC to the Type 45 destroyers, but the request was turned down. There was no money available for the program in the Planning Round, and the news was widely spread over the internet.

However, the graphic, which dates October 2012, confirms that CEC isn’t gone. It is planned to get greater funding from the fourth of the 10 years of the Equipment plan. This sudden increase might indicate fitting of the system to the Type 45s, and the level of spending, which remains high all the way to 2022 (the 10th year), hopefully means that CEC will find its way on the Type 26 as well.     

Small Boats: the money allocated to RHIBs and other boats in service with the Navy (and Marines?)



Type 23 Capability Sustainment Programme

As we have started to see, quite a lot of capabilities of the Type 26 will come from the modernized Type 23s, which will, in this way, also act as testing beds to refine systems and concepts for their successor.

It is expected that the Type 26 will inherit:



·         The Stingray anti-submarine torpedoes, and very possibly the tubes and launcher systems whole

·         The ARTISAN 3D radar (Type 997 for the Royal Navy), with the first having been fit on HMS Iron Duke during her latest refit.

·         The FLAADS(M) Sea Ceptor system with its CAMM missiles. FLAADS stands for Future Local Area Air Defence System (Maritime). It is planned to start replacing the old Sea Wolf on the Type 23s from 2016. 

·         The towed sonar 2087, with the eight set having been installed recently on the 8th Type 23 (HMS Portland, Westminster, Northumberland, Richmond, Somerset, Sutherland, Kent, St Albans)

·         Possibly the 30mm guns



In addition, the Royal Navy is working to develop a Common Combat System, with applications across the whole fleet. This evolutionary approach will eventually lead all the way up to the Type 26’s own system.







CAAM missiles will represent a dramatic improvement from the current Sea Wolf system. Fully fire and forget, faster and more agile, the CAAM has a greater useful range (in excess of 25 km, approaching that of the much more expensive Aster 15) and promises to have an anti-surface attack capability as well, with the capability to engage even Fast Attack Crafts.

MBDA shows on its website a video explaining the future refit that will be carried out on the Type 23 warships to move from Sea Wolf to the new system. The current 32 Sea Wolf tubes will be removed and replaced by just 12 cells, arranged in two rows of six, on the Port side of the existing silo. Each of the six cells will contain a quad-pack of CAMM missiles, giving a total of up to 48 weapons embarked. The cells are not Sylver VLS systems, but a much simpler installation enabled by the Cold Launch feature of the new missile.

The starboard half of the current missile silo will become available for other uses, freeing up invaluable space in a ship type that is inexorably approaching the end of its growth margin. The CAMM installation also enables the removal of the two Sea Wolf radar illuminators and of their bulky under-deck equipment, replacing them with much smaller secure Data Link antennas. The all-weather canisters used by the CAMM missile on the frigates are the same that will be used for use on the truck-mounted launcher intended to replace Rapier in the Army, maximizing commonality.

It is a real bargain: more missiles, more capable, AND precious free space suddenly available for other uses. Without the large mass of the Type 911 Sea Wolf radars, it will even be possible to fit Phalanx CIWS systems on top of the bridge superstructure, and/or on top of the hangar. It won’t necessarily happen, but there will be finally space to make it possible. 

But there is even more. Much of what will appear in the coming years on the Type 23s will then be part of the equipment with which the Type 26 begin their service life. The T23 CSP is part of the Royal Navy Core Budget, funded as part of the 10 year plan. However, most of the T23 CSP components currently sit in the Uncommitted portion of the core budget, as contracts haven’t yet been physically signed.

So, what further improvements are planned for the Type 23s?

 
In the red circle, one of the two Type 911 Sea Wolf radar directors. Their removal will free up valuable space. In the blue circle, the GSA.8 sensor turret, that the Navy hopes to replace soon.
The ULTRA Series 2500 EO/IR turret is the likely preferred option, having already been selected for the Type 45s.



The GSA.8 was also used on the Type 22 B3 (two turrets on each ship). The Type 45s entered service with the much more modern and capable ULTRA Series 2500 Naval EO turret. Two turrets are installed, and they are very easily spotted looking at a photo of the destroyer. A single Series 2500 turret could be fitted to the Type 23s to replace the GSA.8, but so far there has not been a contract award.

DAS-SS: the Type 23 is expected to get the new decoy launcher and, of course, the decoys that will emerge from the various MIDAS-related work streams.

The Type 23s can also expect communications improvements, including Data Link 22, which will in the coming years progressively replace the Data Link 11, introducing Beyond Line of Sight capability that DL11 does not offer.

MEWSS/UAT spiral development will roll in progressive improvements to the Electronic Warfare Support Systems, and under Future Maritime Radar Electronic Surveillance (FMRES) the ships will be fitted with the latest fully digital Radar Electronic Support Measures (RESM) already being fitted to the Type 45 destroyers.

And, of course, the Type 23 will indirectly benefit from improvements to the helicopter fleet: the Merlin HM2 with its vastly greater capabilities, the new Wildcat, and, in good time, the new weaponry, from the M3M heavy machine gun to the Future Anti Surface Guided Weapon (FASGW), both Heavy (Sea Skua replacement) and Light (Thales LMM missile, introducing a new capability, particularly effective against small surface targets). 

As we know there is also a Maritime UAV requirement, to be met via UOR, that should, in the coming months, deliver a contractor-owned, contractor-operated unmanned aircraft system. A first Task Line is wanted for a “RFA vessel” which is undoubtedly the Bay-class LSD based in the Gulf, but a second Task Line is wanted for the Type 23 frigates.

Already in 2006, the Royal Navy trialed Scan Eagle aboard, and demonstrated full level 5 control of the UAV from the ship.  


Don’t write the Type 23s off yet, their best days are yet to come.
